Metabase is an open-source BI tool for building charts and dashboards over MySQL, PostgreSQL, MongoDB, Redshift, and more. This guide deploys Metabase on Kubernetes, loads the Sakila sample dataset into MySQL, builds a dashboard, and secures it behind Nginx Ingress with cert-manager TLS. Prerequisites: a Kubernetes cluster with kubectl / helm configured, a Linux workstation, a reachable MySQL server, and a domain name. Load the Sakila Sample Database Sakila models a DVD rental store — films, actors, inventory, rentals. $ sudo apt install zip -y $ wget https://downloads.mysql.com/docs/sakila-db.zip $ unzip sakila-db.zip Connect to your MySQL server (replace host/port/user): $ mysql -h <HOST_ENDPOINT> -P <DATABASE_PORT> -u <ADMIN_USER> -p mysql > CREATE DATABASE sakila ; mysql > SOURCE sakila - db / sakila - schema . sql ; mysql > SOURCE sakila - db / sakila - data . sql ; Deploy Metabase $ nano metabase.yaml apiVersion : apps/v1 kind : Deployment metadata : name : metabase spec : selector : matchLabels : app : metabase replicas : 1 template : metadata : labels : app : metabase spec : containers : - name : metabase image : metabase/metabase:latest ports : - containerPort : 3000 protocol : TCP --- apiVersion : v1 kind : Service metadata : name : metabase-svc spec : type : LoadBalancer selector : app : metabase ports : - name : http port : 8080 targetPort : 3000 Your cloud provider may need a provider-specific LoadBalancer annotation here (e.g. to set the listener protocol) — check its Kubernetes docs if the default doesn't work. $ kubectl apply -f metabase.yaml $ kubectl get deployments $ kubectl get services Wait for metabase-svc to get an EXTERNAL-IP (can take a few minutes), then visit http://<external-ip>:8080 to confirm the Metabase welcome page loads.

Nginx UI is an open-source web GUI for managing Nginx, single-node or clustered, with real-time stats, automatic Let's Encrypt TLS, performance monitoring, and even LLM-assisted config editing. This guide installs it on Ubuntu 24.04, puts it behind a reverse proxy with TLS, sets up ACME certificate management, and creates a virtual host through the dashboard. Prerequisites: an Ubuntu 24.04 server, non-root sudo user, a domain A record (e.g. nginx-ui.example.com ), Docker installed if you choose that install path. $ sudo apt update $ sudo apt install nginx -y Pick one of the two install methods below. Option A: Install via Script Runs Nginx UI as a system service, managing the host's Nginx directly. $ curl -O https://cloud.nginxui.com/install.sh $ sudo bash install.sh install $ nginx-ui --version $ sudo systemctl start nginx-ui $ sudo systemctl status nginx-ui Option B: Install via Docker Runs as a container — you won't be able to edit the host's Nginx configs directly through it. $ mkdir -p ~/nginx-ui-docker $ cd ~/nginx-ui-docker $ sudo mkdir -p /opt/nginx-ui/nginx $ sudo mkdir -p /opt/nginx-ui/config $ sudo mkdir -p /opt/nginx-ui/www $ nano docker-compose.yml version : ' 3.8' services : nginx-ui : image : uozi/nginx-ui:latest container_name : nginx-ui restart : always environment : - TZ=UTC volumes : - /opt/nginx-ui/nginx:/etc/nginx - /opt/nginx-ui/config:/etc/nginx-ui - /opt/nginx-ui/www:/var/www ports : - " 127.0.0.1:9000:80" networks : - nginx-ui-net networks : nginx-ui-net : driver : bridge $ sudo docker compose up -d $ sudo docker compose ps $ curl -X GET http://localhost:9000 Configure the Reverse Proxy Nginx UI listens on localhost:9000 . Put it behind a public vhost with WebSocket support (needed for live stats/terminal): $ cd /etc/nginx/sites-available $ sudo nano nginx-ui.conf map $http_upgrade $connection_upgrade { default upgrade ; '' close ; } server { listen 80 ; listen [::]:80 ; server_name nginx-ui.example.com ; location / { proxy_set_header Host $

Kubernetes makes it easy to define CPU and memory requests for our applications. But there is a problem: How do we know whether those resource requests are actually correct? If an application requests: yaml resources: requests: cpu: "1000m" memory: "1Gi" but normally consumes only a few millicores of CPU and a few megabytes of memory, we may be reserving significantly more cluster capacity than the workload actually needs. I wanted to understand how Kubernetes cost optimization platforms detect this situation, so I built a small hands-on lab using: Google Kubernetes Engine (GKE) CAST AI Kubernetes Docker FastAPI Google Artifact Registry The goal wasn't simply to install CAST AI. I wanted to observe the complete process: Deploy workload ↓ Observe resource usage ↓ Compare requests vs usage ↓ Identify over-provisioning ↓ Generate recommendation ↓ Apply rightsizing ↓ Verify from Kubernetes Architecture The lab architecture was intentionally simple. FastAPI Coffee API | v Docker Image | v Google Artifact Registry | v GKE Cluster | v Kubernetes Deployment | +----------------+ | | v v Pod #1 Pod #2 | | +-------+--------+ | v ClusterIP Service + | v CAST AI | +-------+-------+ | | v v Cost Monitoring Workload Optimization 1. Building a Small Test Application I created a very small FastAPI application for the experiment. from fastapi import FastAPI import socket import os import time app = FastAPI() @app.get("/") def home(): return { "message": "Coffee Shop API", "hostname": socket.gethostname(), "pod": os.getenv("HOSTNAME"), "time": time.time() } @app.get("/coffee") def coffee(): return { "coffee": "Cappuccino", "price": 120 } The hostname in the response was useful later because I could see which Kubernetes Pod handled each request. 2. Containerizing the API The application was packaged using Docker. FROM python:3.12-slim WORKDIR /app COPY requirements.txt . RUN pip install --no-cache-dir -r requirements.txt COPY app.py . EXPOSE 8000 CMD ["uvicorn", "app:app", "--host", "0

Ghost is an open-source publishing platform with built-in newsletters, memberships, subscriptions, ActivityPub federation, and Tinybird-powered web analytics. This guide covers two install paths on Ubuntu 24.04: Ghost-CLI for a traditional host install, and Docker Compose for a containerized deployment with analytics. Prerequisites: an Ubuntu 24.04 server, non-root sudo user, a domain A record (e.g. ghost.example.com ). Option A: Install with Ghost-CLI Install Node.js Ghost requires Node v22 LTS — check compatible versions before installing elsewhere. $ curl -fsSL https://deb.nodesource.com/setup_22.x -o nodesource_setup.sh $ sudo -E bash nodesource_setup.sh $ sudo apt install -y nodejs $ node -v Install and Configure MySQL $ sudo apt install -y mysql-server $ mysql --version $ sudo mysql_secure_installation Walk through the prompts: enable password validation ( y ), pick strong policy ( 2 ), remove anonymous users ( y ), restrict root to localhost ( y ), drop the test database ( y ), reload privileges ( y ). $ sudo mysql mysql > CREATE DATABASE ghost_db ; mysql > CREATE USER 'ghostuser' @ 'localhost' IDENTIFIED BY 'Your_password2!' ; mysql > GRANT ALL PRIVILEGES ON ghost_db . * TO 'ghostuser' @ 'localhost' ; mysql > FLUSH PRIVILEGES ; mysql > EXIT ; Install Nginx $ sudo apt install -y nginx $ sudo ufw allow 'Nginx Full' $ sudo systemctl status nginx Install Ghost $ sudo npm install ghost-cli@latest -g $ sudo mkdir -p /var/www/html/ghost $ sudo chown $USER : $USER /var/www/html/ghost $ sudo chmod 775 /var/www/html/ghost $ cd /var/www/html/ghost $ ghost install The installer prompts for: Blog URL : https://ghost.example.com MySQL hostname : localhost MySQL username/password/database : from the setup above Set up Nginx? : y Set up SSL? : y (installs acme.sh ) Email for SSL : your address Set up Systemd? : y Start Ghost? : y Manage the Config $ nano /var/www/html/ghost/config.production.json $ cd /var/www/html/ghost $ ghost restart Or via systemd (replace ghost-example

A Patroni cluster needs an odd number of nodes to maintain quorum — with 3 nodes, losing 1 still leaves a majority, so the cluster keeps running. This guide builds a 3-node PostgreSQL cluster on Ubuntu 24.04 with Patroni handling replication and automatic failover, etcd as the coordination store, and HAProxy load-balancing client connections — all secured with TLS. Prerequisites: three Ubuntu 24.04 servers (2 vCPU / 4GB RAM minimum) with PostgreSQL installed, non-root sudo access, and a domain with three A records: node1.example.com , node2.example.com , node3.example.com . Replace these placeholders with your actual subdomains throughout. Install Dependencies Run on all three nodes unless noted otherwise. 1. Install packages: $ sudo apt update $ sudo apt install haproxy certbot pipx -y $ sudo pip3 install --break-system-packages 'patroni[etcd3]' psycopg2-binary psycopg 2. Install etcd: $ wget https://github.com/etcd-io/etcd/releases/download/v3.6.4/etcd-v3.6.4-linux-amd64.tar.gz $ tar -xvf etcd-v3.6.4-linux-amd64.tar.gz $ sudo mv etcd-v3.6.4-linux-amd64/etcd etcd-v3.6.4-linux-amd64/etcdctl /usr/local/bin/ 3. Open firewall ports — 80 (Certbot), 2379/2380 (etcd), 5432/5433 (PostgreSQL + Patroni-managed PostgreSQL), 8008/8009 (Patroni REST API): $ sudo ufw allow 80,2379,2380,5432,5433,8008,8009/tcp $ sudo ufw reload $ sudo ufw status Configure SSL Certificates 1. Request a certificate per node (run on each node for its own subdomain): $ sudo certbot certonly --standalone -d node1.example.com -m admin@example.com --agree-tos --no-eff 2. Create a cert-prep script on each node (set HOSTNAME to that node's subdomain): $ sudo nano /usr/local/bin/prepare-ssl-certs.sh #!/bin/bash HOSTNAME = "node1.example.com" # Update for each node CERT_DIR = "/etc/letsencrypt/live/ $HOSTNAME " ARCHIVE_DIR = "/etc/letsencrypt/archive/ $HOSTNAME " getent group ssl-users > /dev/null || sudo groupadd ssl-users for user in etcd patroni haproxy postgres ; do if ! id " $user " > /dev/null 2>&1 &&

Laravel is a popular PHP framework with routing, authentication, and database management built in. This guide deploys a Laravel app behind Nginx on Ubuntu 24.04, wires it to MySQL, secures it with Let's Encrypt, and builds a small dashboard that queries live data.
